`CLEARER FOR SPINNING-MACHINES.

.SPECIFICATION forming part of Letters Patent No. 534,616, datedFebruary 19, 1895.

Application iled January 22, 1894:. Serial No. 497,636. (No model.)

To all whom t may concern:

Beit known that I, WILLIAM C. PEIRCE, of Providence, in the county ofProvidence and State of` Rhode Island,have invented certain new anduseful Improvements in Clearers for Spinning Machines; and I herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming partof this specitication.

This invention has reference to improvements in clearers for top-rollswhich are particularly adapted for use on roving-frames.

The object of the invention is to construct a clearer, of the naturedescribed, which will act at all times on all the top-rolls.

Another object is to so construct a double clearing-device that it mayreadily be removed from the machine, while it is h eld from movingforward unduly.

The invention consists in the peculiar construction of the clearer-rollsand in the side arms to which they are secured.

The invention also consists in such other novel features of constructionand combination of parts as will hereinafter be more fully described andpointed out in the claims.

Figure 1 represents an end view of therollbracket of aroving-frame-showing the drawing and top rolls with the improved rackand the clearer-device. Fig. 2 represents a vertical sectional view ofthe same to more clearly show the location of the clearer. Fig. 3represents a front elevation of Fig. 1. Fig. 4 is a plan view of theclearer-device removed from the machine.

Similar numbers of reference designate corresponding parts throughout.

In the drawings 5 represents one of the end brackets in which the frontdrawing-roll 6 is journaled, and 7 the adjustable bearing-block in whichthe drawing-rolls 8 and 9 are journaled. Pivoted to the rear ends ofthese adjustable blocks 7 are end-frames 10-10 which are formed in twoparts to allow of their adjustment so that the top-rolls 1l, 12 and 13,

which are j ournaled in bearing-slots in the frames, may be brought tobear on the respective drawing-rolls. From these end-frames lO-lO extendplates let-14 cut away at their upper portions to form arms in which therods diameter.

15 are journaled, and on these rods, within the plates 14:, are clampedthe sleeves 16-16 which prevent the longitudinal movement of the rods.The rods serve as supports for fliers, when not in use, or may be usedfor supporting a dust-shield. On the forward portions of the frames10-10 near the bearings for the rolls 11 arey the Vertical-extensions17-17. 6o

The clearer-device consists of two clearerrolls 18 and 19 connectedtogether by the arms 20-20 which have end sleeves or perfo-V rationsthrough which extend pivots 2l and 22, these pivots being rigidlysecured in the axial centers of the respective clearer-rolls. The arms2O are furnished with stops 23-23 which, when the clearing-device isthrown too far forward, strike the vertical-extensions The rearclearer-roll 18 consists of a shaft 18 having enlarged portions 182 of alength equal to the length of the top-rolls and of a diameter to rest onthe top-rolls 12 and13 and to be readily rotated by the frictionalcontact therewith. On the surfaces of these enlargements is secured thecovering 24 consisting of a spiral band between the coils of which areleft spiral grooves 25. This covering is generally formed of a tape orribbon 8o of textile material having a teaseled surface adapted to takeup the short fibers which adhere to the top-rolls and the edges formselvages which tend to hold the fibers so taken up when the fibers arebrought into contact with the edges.

The clearer-101119 is of a similar construc-l tion 4to the roll 18 butis of a much smaller diameter and rests, in its normal position, on thetop-roll 11 slightly in front of its vertical 9o The central enlargement192 is, however, continued for a length equal to the length of the twocentral top-rolls l1 and for the spacebetween these rolls. The covering26 on the enlargements is arranged in spirals 95 extending the length ofthe enlargements and having grooves 27 between the coils, as in theconstruction of the clearer-roll 18, the material being also similar. Itis, however, evident that dlerent materials or grades of maroo terialmay be used on the clearer-rolls, and textile material, or othersuitable material,

such as leather with a rough surface, or any other material which isadapted to collect the short fibers from the top-rolls.

As the short fibers are carried around by the top-rolls into contactwith the clearerrolls, they are engaged by the covering of these rollswhich, being arranged in spiral coils, exerts a wiping action by theedges of the spiral coils on the top-rolls and also tends to drive thebers toward and into the grooves between the coils of the covering wherethe edges of the covering tend to more securely hold the fibers. Inpractice it is found that when these clearer-rolls are iirst placed inoperation the grooves 25 and 27 become filled before an appreciablethickness is added to the surface of the covering, although at all timesthere is a difference in the density or compactness with which the bersare packed in the grooves and on the surface of the covering, so thatwhen the rolls are completely iilIed, the wiping actionof the spiralcovering is, to an extent, maintained.

of rolls consisting of the rolls 11, 12 and 13 each of which issupported by a corresponding roll in the lower series, and bearings, inwhich the upper series of rolls is journaled, adapted to locate the sameon the lower rolls, of the rear clearer-roll supported by the toprolls12 and 13 and adapted to be driven by frictional contact therewith, sidearms pivoted on studs axially secured in the ends of the rearclearer-roll, and a front clearer-roll rotatably secured between theforward ends of the side arms and supported by the same against thesurface of the top-roll 11 and in front of its vertical axial plane.

2. The combination with the roll 18 having the enlarged portions 182 andprovided with the spiral covering 24, and the pivots 21 axially securedinthe ends of the roll, of the roll 19 having enlargements of a smallerdiameter than those of the roll 18, said enlargements being providedwith spiral coverings studs or pivots 22 axially secured in the ends ofthe smaller roll, and the arms 20-20 having the stops 23-23 andjournaled on the pivots of the respective rolls, as and for the purposedescribed.

In witness whereof I have hereunto set my hand. f
